在结构上

Hydroxysteroid dehydrogenase/carbonyl reductase ( 3α-HSD/CR,EC 1.1.1.50 ) from Comamonas testosteroni is an inducible enzyme which catalyzes the oxidation of androsterone with NAD+ to form androstanedione and NADH. 3α-HSD/CR was a member of the SDRs family, whose crystal structure had been solved by X-ray diffraction in 2000. The structure of 3α-HSD/CR is a homodimer which shows a typical pattern of Rossmann-fold structure consisting of βαβ units, and reaveals similarity with other members upon the SDRs family.

中文摘要 3α-Hydroxysteroid dehydrogenase/carbonyl reductase ( 3α-HSD/CR，EC 1.1.1.50 )是从Comamonas testosteroni菌体中分离而来的诱发性酵素，利用NAD+为辅因子，将受质androsterone氧化成androstanedione并伴随NADH的生成而完成催化反应。3α-HSD/CR是属於SDRs家族成员之一，其立体结构已经在2000年利用X-ray晶体绕射所解出。3α-HSD/CR在结构上为一同源双聚体，并和其它家族成员一样具有βαβ二级结构所叠合组成的Rossmann-fold特徵。

It is found that there exists an obvious prepeak in the low-Q domain (Q=15.7 nm^-^1) of the structure factor. In the X-diffraction pattern, the liquid diffraction curve is corresponding with the solid diffraction curve. There exist the prepeaks for them in the low-Q domain, which shows that there is the comparability in the microstructure between them.

采用紧束缚原子间作用势，利用分子动力学模拟的方法研究了Al5Fe2合金熔体的微观结构，发现在结构因子的小角部分(Q=15.7nm^-^1)出现了一个明显的预峰，并得到X射线衍射实验的进一步印证，在实验测得的合金衍射图样中，液态衍射曲线与固态衍射曲线间存在着很好的对应关系，它们在小角部分都存在峰位，这表明Al5Fe2合金熔体与其固态在结构上存在着很大的相似性。

折叠类型的结构比对研究使用结构比对算法对LIFCA进行了同种折叠类型在结构上的差异性研究，以结构比对为基础得到了折叠类型的多序列比对结果，用于建立折叠类型的模型。3。

First of all, the dissertation proves that the three structures are pairwisely isomorphic—the Boolean Algebra formed by the value range topological space, the Boolean Algebra by knowledge nodes, and the Boolean Algebra by data sub-classes. Thus the essential relations between the three Boolean Algebras are constructed. Furthermore, The three structures have the same multiplying mechanism.

首先，论文从理论上证明了由数值域拓扑空间形成的布尔代数、由知识结点集形成的布尔代数、和由数据子类结构集形成的布尔代数在结构上有两两同构的关系，从而建立了了这三者在本质上的联系，并且论证了它们具有相同的"繁衍"机制。

It is shown that although the phonotactics of the onglides and the neighboring elements does not provide crucial evidence for the status of the glides, postconsonantal onglides are structurally closer to the nucleus based on their weight-carrying behavior in stress assignment.

文中指出，韵核前滑音在结构上属声或属韵并不能由与音节首辅音的组合型态得知，但是此语言的重音规则显示韵核前滑音应带音拍，因此在结构上应与韵核较为接近。

Using VMD software, we performed both structure and sequence analysis based on STAMP (Structural Alignment of Multiple Proteins) among lysozymes of four species: human, chicken, dog and mouse. The result represented that lysozymes of human and chicken have the highest similarities. Our results also demonstrate that the corresponding residues of Ile56 and Asp67 in chicken and human lysozyme have a highly structural conservation.

本研究基于STAMP结构比对算法，使用VMD软件主要从结构角度比较了人、鸡、狗、鼠四种脊椎动物溶菌酶的相似程度及亲缘关系，结果发现鸡的溶菌酶与人的溶菌酶结构最相似，亲缘关系最接近，并且人和鸡的溶菌酶的第56位和第67位两个残基位点在结构上高度保守。
